TUBULAR ELECTRIC POCKET-LAMP.

Specification of Letters Patent.

Patented June 1, 1915..

To all whom it may concern:

Be it known that I, GUSTAV P. HEINRICH,

a subject of the Emperor of Germany, residing at the borough of Brooklyn, Kmgs county,

particular object to improve the circuit.

closing mechanism for the lamp and ele ments cooperating therewith to close the circuit between the battery and circuit closer. r

I will now proceed to describe my inven- I will point out in the appended claims, reference being had to the accompanying draw ing, forming part-there0f, wherein- Figure 1 is an elevation of a lamp-em bodying my improvement; Fig. 2 is a verti' cal sectional view of a portion ofthe la'mp;

Fig. 3 is a detail View, in elevation, showing one of the lamp casmg members; Fig. 4 is an enlarged sectional plan view, the sec'' tion being taken one line 44. in Fig. 2;; and Fig. 5- is an enlarged vertical sectional detail view, the section being taken on a line 5 5 in Fig. 1.

As herein embodied, my improved lamp consists of a plurality of separablv contachably connected at the point 3 bybayonet-joint connections 4, or otherwise. casing, consisting of the members 1 and 2, contains a battery 6, of the dry type, which battery supplies current for the lamp 7, the

lamp 7 being connected to the battery 6 in a manner common to this form of electric.

To convey the current from the spring 8 to the casing members, I provide a tubular conductor 9 having in contact therewith one end of the spring 8, the tubular conductor 9 being insulated from the wall of the casing member 1 by means-of a surrounding sleeve 10 of insulating material, such as fiber, the said conductor 10 and spring '8 being insulited from the end of the member 1 by a pa' 11- The circuit closer consists of a tongue 12 integral with the wall of the casing 1. The

tongue 12 is formed by punching out the wall of the member 1 as at ,13 whereby the resilient tongue 12 is formed. The tongue 12 carries a push-button 14 having a head 15 which will contact with the tubular condue-tor 9 when said tongue is pressed in wardly. The insulating sleeve 10 is provided with an opening 16 subjacent the tongue 12 which allows the movement of the tongue 12 to take place so that the head i 15 maycontact with the conductor 9. The tion indetail, the novel features of which' interposition of the tubular ing member 1 and. the tubular conductor 9 also serves .to keepthe tongue 12 and head 15 thereon normally out of contact with the conductor 9. v A further feature of my improvement consists of a clip 17 having a tongue 18f for holding the lamp in a pocket. The clip 17 is secured to the casing member '1 as at 18 and-19. The body or band portion of the c1ip17 is provided with an opening 20 through which the push button 14 protrudes.

The body of the clip 17 is positioned over the tongue 12 and acts to protect the same 7 and also cover the slot-like opening 13 to nected tubular casing members 1 and 2, de-"- prevent the entrance of foreign matter qvhich might short-circuit the battery 6. The

Having now described my invention what Iclaim and desire to secure by Letters Patcut, is:

1. An electric pocket-lamp. comprising a casing consisting of a plurality of detachably connected members, one of said members being cut away to form a yieldable tongue, a tubular conducting element with in the casing member carrying the tongue. insulating material located between said conducting element and the casing member which carries the same, a circuit closer car- 1 ried by said. tongue and normally out of contact with the conducting material, said insulating material being cut away in-line with said circuit closer whereby saidcontact can be caused to impinge upon said insulating sleeve 10 between the inner wall of the cas- "conducting element and the casing member which carries the same, a circuit closer carried by said tongue and normally out of contact with the conducting material, said insulating material being cut away in line with said circuit closer whereby said contact can be caused to impinge upon said conducting material, a lamp carried by said casing, a battery within the casing in circuit with said lamp and the conducting element within said casing, and aiastening device. se-

cured to one of said casing members consisting of a clip and a resilient tongue carried thereby, said clip covering the cut out portion invthe casing memberto which it is secured, said clip being also provided with an opening for the passage therethrough of the circuit closer carried by said tongue.

3. An electric pocket-lamp consisting of a casing arranged to contain a battery, said casing being cut away to form a resilient tongue, a circuit closer carried by said tongue, arranged to close the circuit between said battery and said casing when said tongue is forced inwardly, conducting means within said casing in circuit with said battery but normally out-of contact with said circuit closer, and a fastening device carried by said casing and located over said tongue and covering the cut out portion adjacent the tongue, said fastening device having an opening in the body thereof through which the circuit closer can be manipulated.

4. An electric pocket-lamp, comprising a casing, said casing being cut away to form a yieldable circuit-closing tongue, a lamp carried by said casing at one end thereof, a battery within said casing having its carbon-pole in contact with one of the circuitmembers of the lamp, insulating material between thebattery and said casing, a metallic conductor located between the battery and the insulating material but out of contact with the battery, and an electrical conductor contacting with said metallic conductor and the zinc end of said battery, said insulating material being provided with an opening alining with the circuit-closing tongue whereby said tongue -can be caused to contact with said metallic conductor.

Signed at New York city, N.,Y., this 19th day of January, 1915.
